Keeping Standards up-to-date
Standards are living documents which reflect progress in science, technology and
systems. To maintain their currency, all Standards are periodically reviewed, and
new editions are published. Between editions, amendments may be issued.
Standards may also be withdrawn. It is important that readers assure themselves
they are using a current Standard, which should include any amendments which
may have been published since the Standard was purchased.
Detailed information about joint Australian/New Zealand Standards can be found by
visiting the Standards Web Shop at www.saiglobal.com.au or Standards New
Zealand web site at www.standards.co.nz and looking up the relevant Standard in
the on-line catalogue.
For more frequent listings or notification of revisions, amendments and
withdrawals, Standards Australia and Standards New Zealand offer a number of
update options. For information about these services, users should contact their
respective national Standards organization.
We also welcome suggestions for improvement in our Standards, and especially
encourage readers to notify us immediately of any apparent inaccuracies or
ambiguities. Please address your comments to the Chief Executive of either
Standards Australia or Standards New Zealand at the address shown on the back
cover.
This Standard was issued in draft form for comment as DR AS/NZS 61000.4.34.

PREFACE
This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee
EL-034, Power Quality to supersede AS/NZS 61000.4.34:2007.
The objective of this Standard is to establish a common reference for evaluating the immunity of
electric and electronic equipment when subjected to voltage dips, short interruptions and voltage
variations.
This Standard is an adoption with national modifications and has been reproduced from
IEC 61000-4-34 Ed.1.1 (2009), Electromagnetic compatibility (EMC)—Part 4-34: Testing and
measurement techniques—Voltage dips, short interruptions and voltage variations immunity tests for
equipment with mains current more than 16 A per phase, and has been varied as indicated to take
account of Australian/New Zealand conditions.
Variations to IEC 61000-4-34:2009 are indicated at the appropriate places within this Standard.
Strikethrough (example) identifies IEC text, tables and figures which, for the purpose of this
Australian Standard, are deleted. Where text, tables or figures are added, each is set in its proper place
and identified by shading (example).
IEC 61000-4-34 Ed.1.1 (2009) consists of the IEC 61000-4-34 Ed.1.0 (2005) and its amendment 1
(2009). A vertical line in the margin of the document shows where the base publication has been
modified by amendment 1.
As this Standard is reproduced from an International Standard, the following applies:
(a)
Its number appears on the cover and title page while the International Standard number appears
only on the cover.
(b)
In the source text ‘this part of IEC 61000’ should read ‘this part of AS/NZS 61000’.
(c)
A full point substitutes for a comma when referring to a decimal marker.
The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of
the annex to which they apply. A ‘normative’ annex is an integral part of a Standard, whereas an
‘informative’ annex is only for information and guidance.

AUSTRALIAN/NEW ZEALAND STANDARD
Electromagnetic Compatibility (EMC)
Electromagnetic compatibility (EMC)
Part 4.34:
Testing and measurements techniques—Voltage dips, short interruptions
and voltage variations immunity tests for equipment with mains current
more than 16 A per phase
Any table, figure or text of the international standard that is struck through is not part of this
standard. Any Australian/New Zealand table, figure or text that is added is part of this
standard and is identified by shading.

Scope
This part of IEC 61000 defines the immunity test methods and range of preferred test levels
for electrical and electronic equipment connected to low-voltage power supply networks for
voltage dips, short interruptions, and voltage variations.
This standard applies to electrical and electronic equipment having a rated mains current
exceeding 16 A per phase. (See Annex E for guidance on electrical and electronic equipment
rated at more than 200 A per phase.) It covers equipment installed in residential areas as well
as industrial machinery, specifically voltage dips and short interruptions for equipment
connected to either 50 Hz or 60 Hz a.c. networks, including 1-phase and 3-phase mains.
NOTE 1
Equipment with a rated mains current of 16 A or less per phase is covered by publication IEC 61000-4-11.
NOTE 2 There is no upper limit on rated mains current in this publication. However, in some countries, the rated
mains current may be limited to some upper value, for example 75 A or 250 A, because of mandatory safety
standards.
It does not apply to electrical and electronic equipment for connection to 400 Hz a.c.
networks. Tests for equipment connected to these networks will be covered by future IEC
standards.
The object of this standard is to establish a common reference for evaluating the immunity of
electrical and electronic equipment when subjected to voltage dips, short interruptions and
voltage variations.
NOTE 1
Voltage fluctuations are covered by publication IEC 61000-4-14.
NOTE 2 For equipment under test with rated currents above 250 A, suitable test equipment may be difficult to
obtain. In these cases, the applicability of this standard should be carefully evaluated by committees responsible
for generic, product and product-family standards. Alternatively, this standard might be used as a framework for an
agreement on performance criteria between the manufacturer and the purchaser.
The test method documented in this part of IEC 61000 describes a consistent method to
assess the immunity of equipment or a system against a defined phenomenon. As described
in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC.
As also stated in Guide 107, the IEC product committees are responsible for determining
whether this immunity test standard should be applied or not, and if applied, they are
responsible for defining the appropriate test levels. Technical committee 77 and its subcommittees are prepared to co-operate with product committees in the evaluation of the value
of particular immunity tests for their products.
